I think that the monarchy would care as the UK obviously means a great deal to them but wonât cause too much concern so long as Scotland and Northern Ireland do not become republics. The UK and British monarchy are two very different institutions.
A series is a summation performed on a list of numbers. Each term is added to the next, resulting in a sum of all terms. Sigma notation is used to represent the summation of a series. In this form, the capital Greek letter sigma $\left ( \Sigma \right )$ is used.
Interval Notation. A notation for representing an interval as a pair of numbers. The numbers are the endpoints of the interval. Parentheses and/or brackets are used to show whether the endpoints are excluded or included. For example, [3, 8) is the interval of real numbers between 3 and 8, including 3 and excluding 8. Note: Many authors use reversed brackets instead of parentheses.
